David A. Norcross (born March 30, 1937) is an American Republican Party politician who ran for United States Senate in 1976 and served as chairman of the New Jersey Republican State Committee.
Norcross was born in Camden, New Jersey in 1937. He received his B.A. from University of Delaware in 1958 and his LL.B from University of Pennsylvania in 1961. He served in the United States Army in the Judge Advocate General's Corps, stationed in Asmara, Ethiopia from 1962 to 1965.
He was executive assistant to Governor William T. Cahill from 1971 to 1973, when the New Jersey Election Law Enforcement Commission was created. He became the commission's first executive director, serving from 1973 to 1976.
In 1976 Norcross ran as the Republican candidate for United States Senate against the incumbent Harrison A. Williams. A relative unknown, he used his expertise in campaign financing to attack Williams for what he said were unethical fundraising practices. Norcross was soundly defeated, but Williams would later be convicted of bribery and conspiracy in the Abscam scandal.
He was selected by State Senator Raymond Bateman, then the Republican candidate for Governor of New Jersey, to replace Webster B. Todd as chairman of the New Jersey Republican State Committee in 1977.
